Amazon Prime: Is it worth $99 a year?

Try Amazon Prime Free

I received the following email from Amazon this morning alerting me that the price of Amazon Prime was increasing from $79 to $99 a year:

Dear CacheFreeTV,
We are writing to provide you advance notice that the price of your Prime membership will be increasing. The annual rate will be $99 when your membership renews on August 5, 2014.

Even as fuel and transportation costs have increased, the price of Prime has remained the same for nine years. Since 2005, the number of items eligible for unlimited free Two-Day Shipping has grown from one million to over 20 million. We also added unlimited access to over 40,000 movies and TV episodes with Prime Instant Video and a selection of over 500,000 books to borrow from the Kindle Owners' Lending Library.

For more information about your Prime membership, visit our Prime membership page.

Sincerely,
The Amazon Prime Team

From the website- If your membership renews before April 17, 2014, you'll be charged at a membership rate of $79. If your membership renews on or after April 17, 2014, you'll be charged at a membership rate of $99.

While I've enjoyed Amazon Prime for the past 2 years, I have to make a choice between Netflix at $94 a year and Amazon Prime benefits at $99 (Free prime videos, Prime 2 day shipping, Kindle lending library). I think Netflix is a better value for my family, given that Netflix has a bigger library (including Disney), I can still get free shipping from Amazon if I order $35 at once, and I can get plenty of content for my Kindle for free on Amazon and the internet. I also have a Sam's club membership so I can get good deals there. I went to Amazon and selected "Remind Me Later - Remind me three days before my membership renews".

Sorry, Amazon. I'm out as of August, 2014.

If you're an Amazon Prime member, is it worth $99 a year to keep your Prime membership? Share your thoughts, please.
